MAKING FLAT MATCH-SLAIBS.

Specification of Letters Patent.

Patented Aug. 19,1913.

Application filed February 13, 1913. Serial N 0. 748,214.

To all whom it may concern Be it known that I, THEODOR VON DEY- LEN, manufacturer, a subject of the King of Prussia, and resident of Visselh'ovede, Province of Hanover, Prussia, Germany, have invented new and useful Improvements in the- Making of Flat Match-Slabs, of which the followlng is a specification.

The present invention relates to a new method of making so called waistcoat matches of wood in form of small slabs.

The object of the present invention is to allow of making these matches with very long and very strong heads.

With this object in view, the matches are set like the teeth of a saw, that is, the heads are bent alternately to the right and the left, so that the heads of the one slab will lie in two parallel planes.

The method of setting comb-like strips of matches has been already known in making matches of paper. This method can, however, not be employed with matches made of wood, as, owin to the elasticity of the wood, it is impossible to deform the wood so far, that the matches would not return from theirthus produced position without special arresting means being pro vided. According to the present invention this setting is effected in the dipping frame, or the dipping frame is constructed in such a manner, that it spreads the strips when they are introduced and holds them in such spread position. By such means it is possible to dip the sticks, while they are in such a spread osition, dry and finish them. The

notches or the pyrophorous heads may therefore be made considerably closer, as the notches with this new method need not be larger, that the pyrophorous compound on the heads will make up. As the notches are made smaller, the point for the head will be larger and wider, and can therefore also take more of the pyrophorous compound. After the heads have dried, they are returned into the lane of the slab, and the thickness of the eads may be easily so dimensioned, that the heads will almost touch each other. It is therefore possible, to

make matches of the hereinbefore described kind, each head of which is perfectly rounded, and the heads of which almost touch each other. This is of advantage in that, 'by my process, it will be possible to produce in wood what was heretofore attainable, to

a very inferior degree, only in a,paper manufacture; thus utilizingthe better material to provide a strong match, the head of.-

which resists breaking during the striking operation. It is therefore possible to make the socalled windproof matches, which hitherto could notbe made in such flat form, in this form by means of the new method.

The invention furthermore relates to an arrangement for carrying out the new method with advantage, which is described in the following, reference being had to the accompanying drawings.

In these drawings Figure 1 is a slab of wood, seen from above, which has been divided by suitable incisions into a plurality of strips for forming matches. Fig. 2 is the same slab seen from the side. Fig. 3' is a top view of a part of the dipping frame for mechanically performing the method. Fig. 4 is a side view of the dipping frame. Fig. 5 is a side view of a slightly modified form of my invention. Fig. 6 is a top plan view of the same. Fig. 7 is a side elevation of a further modification. Fig. 8 is a top plan view of the same. Fig. 9 1s an end elevation of a modified form of clamping boards. Fig. 10 is a top plan view of the same. Fig. 11 is a detail view. Fig. 12 is an end elevation of m improved sto plate, and Fig. 13 is a side elevation o one of the clamping boards disclosing the methodof positioning the slabs by means of the stop plates.

With reference to Figs. 1 and 2 it is evident, that the method consists thercin that,

a slab of wood of the ordinary kind is split in the usual manner at one or both ends into the'individual match sticks. The first, third, fifth stick are marked a, the second, fourth, sixth and so on are marked a. Then the st-icksare bent singly, out of the plane of the slab, so that the first, third, fifth and so on stick a is bent to the one side, and the second, fourth, sixth and so on stick a is bent to the other side. In this position the sticks are then secured in any suitable manner. Now they are dipped, for forming the heads. After dipping they are bent back into the plane of the'slab, so that the heads touch or almost touch each other. The sticks will generally spring back by themselves into the plane. of the slab when the means employed for keeping them in the bent position is removed.

The bending aside of the head ends from the plane of the slab may be automatically effected by means of the dipping frame shown in Figs. 3 and 4:. For this purpose the dipping frame is composed of several boards d, which are thicker in the middle than at their upper and lower edge. At the upper and lower edge serrated metal plates or combs are provided. The spaces between the teeth are a little larger than the width of the match sticks, the teeth being correspondingly less wide so that one tooth and one space are together twice as wide as one stick. If now a split slab is placed between two such boards and the latter are pressed together, so that the teeth of the one board enter into the spaces between the teeth of the other board, the sticks a will be bent to the right and the sticks a to the left. In this position the sticks then may be dipped. The sticks may also be locked in this-spread position by means of an auxiliary piece of wood inserted between them whereupon the slab is removed from between the boards and is dipped by hand or in special dipping frames, whereupon the spreading stick is removed. The serrated metal plate may also be used in such a manner, that it forces the one half of the sticks from the plane of the slab, whereupon these spread sticks are locked in position by an auxiliary stick inserted or the like.

Figs. 5 and 6 are side view and plan respectively of a frame or the boards by means of which the sticks can be automatically spread. These boards are here made so that the slabs will be held in the middle and the point of the maximum bend is fixed. To the top and bottom of the boards at serrated bars f are provided.

In the constructional form of the arrangement shown in Figs. 7 and 8 in section and plan respectively the central web consists of a piece of metal d. This allows of male ing the spreading device in a very cheap manner.

Figs. 9 and 10 are section and lan respectively of a constructional form, in which the sticks are supported along their entire length, and in particular along the bent over portion. For this purpose the boards d have alternating recesses (Z and teeth (Z For facilitating the proper adjustment of the slabs with regard totheir sticks and the teeth, it is advisable to provide stops against which the edges of the slabs are laid. These stops may, as shown in Fig. 1] be pressed in one piece with the combs. The stops are marked 7:. in Fig. 11. However, the stops may also be arranged separately from the combs and clamping boards, and to this end I provide the frame shown in Figs. 12 and 13 carrying the stops H which are inserted sidewise over the clamping boards, as shown, to properly position the slabs with respect to the combs. After the clamping has been properly effected, the stop frames may be removed.

It is obvious, that the sticks may be spread also in more than two rows. In this case combs with teeth of different lengths will have to be used. The temporary spreading of the heads may also be obtained by temporarily drawing the slabs apart, so that the heads 0 of the sticks which are to be dipped are on a larger circle than the ends of the sticks.

I claim:

1. A method of making flat match slabs, the sticks of which are alternately set to the right and left, consisting in the said match slabs, made of wood, being clamped in dipping frames, which will simultaneously with the clamping also spread the sticks, and the said sticks being held in such spread condition until they have been dipped and dried.
